Indoor air quality folk - I'm looking for published papers with experimental measurements of PM2.5 in US school cafeterias and I've found.... none!? If you know of any, let me know!

This semester I am on parental leave (and recovering from some health issues). I have been taking a short break from content creation for social media, so bear with me as I've been a bit slow to get properly started with sharing content on Mastodon... Expect more from me in the new year! But, for now, a bit of a break from social media (and news in general) has been... refreshing.

Introduction:
I’m an environmental engineer and professor at CU Boulder. I work with aerosols (tiny particles in air that are bad for you to breathe), especially in indoor air.
